We got a sneak peek at the new Amazon Go store opening at Brookfield Place in New York City.

With a swipe of your phone's Amazon Go app, you enter the store and are tracked as you make selections for purchase. When you walk out, the charge shows up on your account without any interaction with a cashier. However, Amazon is now offering cash sales through an associate on request.

For example, you'd have to wait in a long line at Dominique Ansel to even get close to purchasing one of its famous cronuts-- or better yet, the lesser known but even more delicious DKA pastry, as seen here.
